2 Claims.

This invention relates to a mobile ground working device, such as ashovel, plow or cultivator, but more particularly to the body-part orsupporting frame of the-device and a combined draw-bar andbrace elementfor said body-part, and is a division of our joint application'filedJune 1, 1935, Serial No. 24,553. 1

The object of the invention is to provide, in a. manner as hereinafterset forth a mobile ground working device body-part or supporting framehaving means to permit of expeditiously connecting to the bottomthereof, in spaced relation coupling elements for ground working tools.

A further object of the invention is to provide, in a manner ashereinafter set forth, a ground working device with a verticallyadjustable body part or supporting frame carrying a combined draw-barand brace element having vertically adjustable hitching means, and withsaid element so disposed to insure the square and rigid construction ofthe body-part, as well as to permit the maintaining of any level -of thebody part and ground working tools, with the load on the draw-,bar, thusmaking it adjustable for high or low hitches and equalizing the heightso as to not interfere with the utility of the device,

as well as the load pulled behind the latter.

A further object of the invention is to provide, in a manner ashereinafter set forth a mobile ground working device body part orsupporting frame having means for connecting thereto hangers forvertically adjustable rotatable suspension means therefor.

Further objects of the invention are to provide, in a manner ashereinafter set forth a structure embodying body-part or supportingframe and a combined draw-bar and brace element for a verticallyadjustable mobile ground working device which is simple in itsconstruction and arrangement, strong, durable, compact, rigid, readilyassembled, thoroughly efiicient in its use, and inexpensive tomanufacture.

To the above ends essentially, and to others which may hereinafterappear the invention consists of such parts, and such combination ofparts which fall within the scope of the invention as claimed.

In the' drawing:

Figure l is a top plan view of a vertically adjustable mobile groundworking device provided with a body-part or supporting frame and acombined draw-bar and brace element in accordance with this invention;

Figure 2 is a side elevation of the body part or supporting frame andthe combined draw-bar and brace element, theelevating and lowering meansfor the body part or supporting frame not shown;

Figure 3 is a section on line 3-3 Figure 2; and

Figure 4 is a section on line 4-4 Figure 3,

The body-part or supporting frame of the device will be hereinaftertermed a skeleton body and is generally indicated at 5. Each side ofbody 5 has connected tothe front thereof a rearwardly extendingdownwardly disposed angle- 5 shape hanger 6 carrying at its lower end asupporting wheel I. Attached to each side of the body 5 and to a hanger6 is a means 8 for shifting the hangers in a direction to elevate orlower the wheels 1 whereby the body 5 will'be elevated or lowered withrespect to the ground level. Coupled to the body 5 as at 9 are rows ofspaced ground working tools ID. The construction and arrangement of-thehangers, wheels, means 8, couplers for the tools I and the tools I0 willbe as set forth in the application aforesaid.

The body includes a set of spaced elongated parallel I-beams I I ofthesame length and height and a pair of inwardly opening oppositelydisposed channel irons I2 which overlap the ends of top and bottom facesof the I-beams II. The channel irons I2 are anchored at their forwardends to the forward I-beam I I by the holdfast means I3. The channelirons I2 areanchored, at their rear ends to the rear I-beam II by theholdfast means I 4. Each channel iron in proximity to'its forward end isformed with an opening I5 disposed rearwardly of and in close proximityto the web I6 of the front I-beam II. The ends ofv the channel irons I2are flush with the forward edges of the front I-beam II and with therear edges of the rear I-beam II.

Sleeves II extend through the openings I5, project inwardly andoutwardly with respect to channel irons I2 and are anchored stationaryto the web I6 in any suitable manner, preferably in a manner as setforth in the application aforesaid. The upper or forward ends of thehangers 6 are journaled in the sleeves II.

The combined draw-bar and brace element or structure is generallyindicated at I8 and it includes an I-beam I9 which constitutes a drawbarand is formed of a straight rear stretch 20 and a downwardly inclinedfront or forward stretch 2I of materially greater length than stretch20. The bottom of stretch 20 is welded or otherwise secured upon the topof body 5 at the transverse center of the latter. The length of stretch20 is such that its front and rear ends will be flush with the front andrear edges respec- 50 tively of the body 5. The element or structure I 8includes a pair of oppositely disposed bracing bars 22, 23 of anglecontour and each formed of a vertical and a horizontal leg 24, 25respectively. The legs 24 extend outwardly at right angles to 55 thebottoms of legs 25. The bars 22, 23 are of less length and height thanthat of the I-beam I9. Each angle bar is formed of a straight rearstretch 26 and a downwardly and inwardly inclined forward stretch 21 ofgreater length than stretch 26. 6p

retaining pen 36.

The bottom of a stretch 26 is welded or otherwise secured upon the topof body 5 between the transverse center and a side edge of. said body.The length of the stretches 26 is such that the front and rear endsthereof will be flush with the front and rear edges of body 5. Theforward and terminal portion of the legs 25 of the stretches 211 is cutaway. The forward end terminal portions of the legs 24 of the stretches21 are arranged against opposite sides of the web of the Ibeam l9rearwardly adjacent to the forward end of. the latter and are anchoredto such web by the holdfast means 28. I

The stretch 20 of I-beam l9 and the stretches of the bars 22, 23constitute bracing means for insuring the square and rigid constructionof the body 5, as well as preventing the twisting of the latter.

The element or structure I8 includes an adjustable hitching meanscarried by the forward end of I-beam I9. The said means includes a pairof spaced parallel T-shape supporting members 29, each having the headand stem indicated at 30, 31, respectively. The heads 30 are verticallydisposed, extend above and depend below and oppose the forward end edgeof I-beam I9. The stems 3| are arranged at opposite sides of the web ofI-beam l3 and are anchored thereto by the holdfast means 32. Each head39 is formed with a vertical row of spaced openings 33. The openings ofone row in one head align with the openings of the row in the other end.The said means includes a coupling pin 34 for selectively positioning inthe pairs of aligning openings and when so positioned is supported andconnected by the members 29 to the I-beam l9. Extended forwardly fromthe members 29 and connected to the latter by the pin 34 is a clevis 35carrying a The openings 33 in connection with the pin 34 provides forthe vertical adjustment of the clevis.

The manner of setting up of the I-beam I9 and bars 22, 23, in connectionwith the apertured supporting members 29 and a pin 33 provide for themaintaining of any level of the body 5 and ground working tools, withthe load on the draw-bar and provision is had for high or low hitchesand equalizing the height so as not to interfere with the utility of theground working device, as well as the load pulled behind the latter.
